Description
Technical Field
The invention relates to a closestool flushing device, in particular to an active water inlet core valve of an air energy flushing closestool widely used in human daily life
Background
The invention mainly aims at the technical proposal of 2018202112359 which is issued by the utility model patent under the name of the inventor to carry out optimization and improvement.
Disclosure of Invention
The invention aims to solve the technical problem of providing a more advanced active water inlet core valve of an air energy flushing closestool aiming at the technical current situation.
The invention solves the technical problems by adopting the technical scheme that the active water inlet core valve of the air energy flushing closestool is technically improved aiming at the water inlet mode of the core structure working cavity of the core valve, namely a special water inlet pipeline is added, and the only original mode of passively feeding water from the bottom of the valve core of the core valve is not adopted.
The invention provides two water inlet schemes, but the final purposes of the two schemes are water delivery into the working cavity of the core valve, and the two schemes have the same return in a special way.
Drawings
Fig. 1 is a structural sectional view of a first embodiment of an active inlet spool valve for an air energy toilet, and fig. 2 is a structural sectional view of a second embodiment of the active inlet spool valve for an air energy toilet.
Detailed Description
The invention will be described in further detail below with reference to the accompanying drawings:
the structural principle and the working principle of the invention are explained as follows:
the air can the flush toilet initiatively advance water tank 2 of core valve in arrange a core valve, this core valve comprises disk seat 4, valve gap 5, valve rod 6, case 7, side opening 13, inlet aperture 8, discharge orifice 14, spring 9, spring two 10, main part such as spring three 15, sets up a working chamber in the core valve, this working chamber by the bottom of valve gap 5, the center department of disk seat 4 and the top surface of case 7 enclose.
When the air can the flush toilet initiatively advance water core valve's main inlet tube 1 and insert the water pipe network after, the running water is under self pressure effect, gets into the bottom depths of water tank 2 by main inlet opening 12 automatically to fill the inside predetermined space of water tank 2 gradually, and begin up the extrusion incasement air from the bottom of water tank 2, until equal back with external water pressure, stop intaking, the water level reachs the design water level.
Meanwhile, a water inlet branch 3 is opened at the main water inlet hole 12 of the active water inlet core valve of the air energy flushing toilet, and the water inlet branch 3 is directly communicated to a small water inlet hole 8 of the valve seat 4, which is formed in the working cavity, and enters the working cavity of the active water inlet core valve of the air energy flushing toilet.
When the water storage pressure of the working cavity of the air energy flushing closestool active water inlet core valve is the same as the pressure of a tap water pipe network, water can not enter any more.
Once a person presses the valve rod 6 of the active water inlet core valve of the air energy flushing toilet, a small amount of water in the working cavity is rapidly ejected from the central hole of the valve rod 6, meanwhile, the flow rate of the small water inlet hole 8 is far smaller than the flow rate of the discharge hole 14 on the valve rod 6, so the pressure in the working cavity is rapidly reduced, the pressure at the bottom of the valve core 7 is still greater than the pressure in the working cavity, because the valve core 7 adopts an inverted cone structure, the bottom thrust of the valve core 7 is added with the elastic force of the spring III 15, the two forces are combined to rapidly lift the valve core 7 to move upwards, a main jet flow channel at the bottom of the valve seat 4 is opened, a large amount of water in the water tank 2 is rapidly ejected from the side hole 13 at the bottom of the valve seat 4 and enters the toilet to finish a flushing action, then, the valve rod 6 is restored to the original position upwards under the restoring action of the spring II 10, and the spring III 15 is used for prolonging the upward moving stroke of the valve core 7, the lifting is higher, the damping effect is achieved, the first spring 9 is compressed after the valve core 7 moves upwards, and the first spring 9 mainly serves as a top dead center limiting valve core 7.
After one-time flushing is finished, the valve core 7 is forcibly pushed downwards by a spring I9 in the working cavity of the air energy flushing closestool active water inlet core valve (although the elasticity is small), meanwhile, the water inlet branch 3 of the air energy flushing closestool active water inlet core valve immediately forcibly replenishes water into the working cavity, and the pressure generated by newly-entered replenishing water rapidly extrudes the valve core 7 downwards, so that the valve core 7 of the air energy flushing closestool active water inlet core valve moves downwards under the action of the resultant force, and the valve core 7 is inverted-cone-shaped, so that in the downward moving process, the valve core 7 is limited and blocked by a flange in the valve seat 4 to automatically stop, and the sealing ring groups 11 respectively realize sealing between the valve rod 6 and the valve cover 5, sealing between the valve rod 6 and the valve core 7 and sealing between the valve core 7 and the valve seat 4 (one position above and below). After sealing is completed, the water level in the water tank 2 begins to rise and compress the internal air, and water storage and pressure boosting are started.
The present embodiment is different from the technique disclosed in 2018202112359 in the authorized name of the person: the working cavity water inlet mode of the active water inlet core valve of the air energy flushing closestool is changed from the original mode of water inlet from the bottom of the valve core 7 upwards to the mode of water inlet from a tap water pipe network through the water inlet branch 3, and the air energy flushing closestool has the advantages that:
the valve core 7 of the active water inlet core valve of the air energy flushing closestool can upwards feed water from the bottom of the valve core 7 in the downward moving process under normal conditions, but if the residual water pressure at the bottom is higher, the valve core 7 can be upwards supported, the water in a working cavity is difficult to feed, the internal pressure cannot be quickly established, the closing time of a bottom jet outlet of the valve seat 4 is delayed or the bottom jet outlet cannot be smoothly closed, and the bottom jet outlet cannot work.
After the core valve adopts a core water inlet mode, the pressure in the working cavity of the air energy flushing closestool active water inlet core valve is completely the same as the pressure of a tap water pipe network, and the pressure is inevitably greater than the bottom pressure of the valve core 7 (no matter whether water is retained or not), so that the valve core 7 can be forced to move downwards by strong thrust formed by the pressure in the working cavity, the sealing action of the whole device is completed, and the working reliability of the device is greatly improved.
After the core valve adopts the water inlet mode, no special requirement is made on the material of the valve core 7, and convenience is brought to production and manufacturing.
Of course, the way of delivering water directly to the working chamber of the active water inlet core valve of the air energy flushing toilet further includes vertically opening a hole downwards from the bottom of the valve cover 5, and delivering the water downwards from the top, and the implementation convenience degree is mainly seen, and the invention is not described herein again.
In order to adapt to a low water pressure area, the embodiment can also adopt a structure shown in fig. 2, and is different from the structure shown in fig. 1 in that the main water inlet pipe 1 in fig. 1 starts to split in the water tank 2, if the water pressure of a use area deviates from the design pressure, the water flow time entering a working cavity deviates from the design value and is difficult to adjust, and the main water inlet pipe 1 is divided into two paths outside the water tank 2 in fig. 2, wherein one path directly enters the water tank 2 and is called as a main water path; one branch is directly led into the working cavity of the active water inlet core valve of the air energy flushing closestool after passing through the water tank 2 through the special water inlet branch 3; in the water inlet mode shown in fig. 2, if the resistance of the main water path is small, a threshold valve or a flow distribution pipe can be connected in series with the main water path, that is, the main water path is opened only when a certain pressure is met, so that the closing time of the core valve can be adjusted at any time according to the tap water pressure of a use area, and the operation is convenient.
Regarding the amount of flushing water: the air energy flushing closestool initiative water inlet core valve, its volume of flushing that opens once mainly comprises two parts: the water storage capacity of the working cavity and the net water storage capacity of the water tank 2 are achieved; the water storage capacity of the working cavity is far less than that of the water tank 2, and the water tank 2 stores waterThe water quantity calculation mode is as follows: due to the existence of the damping spring III 15, the compression resistance delays the closing time of the valve core 7 (which is also necessary), when the resistance is gradually smaller than the pressure stored by the inlet water in the working chamber, the valve core moves downwards, and at the moment, a certain amount of water is stored at the bottom of the water tank 2, and the former water amount is assumed to be V1The part of water will exhaust part of air in the water tank 2, until the valve core 7 closes the main drainage channel completely, the pressure in the water tank 2 will rise gradually, until the pressure is equal to the pressure of the main water inlet pipe network, the water will stop entering, if the initial volume of the water tank is V0The core valve occupies a space V2The volume of the working chamber is V3The main water inlet pressure is P1The resistance of the damping spring III is P2When the initial pressure of water storage in the water tank is (P)1-P2) The ambient air pressure is about 0.1MPa, and the water storage capacity is as follows:
is the amount of flush water available to the device; this is theoretical, and in fact, physics teaches that firstly oxygen in the air is readily soluble in water, and furthermore, the rate of dissolution of the gas is proportional to the amount of dissolution and its pressure (back pressure), so that, in a pressurized closed container, the soluble gas components are rapidly transferred to the water, and the longer the dwell time, the more the absolute amount of dissolution, the less the mass of the closed gas, the more the volume of complete recovery is greatly reduced, resulting in the inability to completely discharge the stored water, the corresponding reduction in the actual water output, and therefore, the actual available flush water volume is dynamically variable, the above formula calculation results are only possible clockwise maximums, which are practically impossible to achieve, and even if the toilet entry time is short, the gas volume is immediately reduced, and the general trend is less and less, the dynamic air volume reduction in the tank 2 is difficult to supplement in real time, but can be compensated by static air supply measures.
The static air supplement refers to air supplement when the device does not work, and the specific method comprises the following steps:
a low-voltage control valve (not shown in fig. 1 and 2) is connected in series with the main water inlet pipe 1 of the water tank 2, and then is connected with a household water pipe. And this control valve and bathroom's illumination or fan synchronous working just so can carry out independent control or interlocking control to the intaking of water tank 2, that is, when needing to use this device, just open into water, when not using, just close into water, this both is applicable to frequent service environment, also is applicable to accidental service environment, and the benefit of doing so is: after having used the squatting pan at every turn, when closing bathroom fan or illumination, just also in the same time the main water intake pipe who has closed this device in the same direction as taking, water tank 2 just no longer intakes, this device is in unoperated state promptly, at this moment, three 15 springs lift case 7 and shift up under the effect of self restoring force, just opened the mainstream passageway naturally, the back is opened to the mainstream passageway, just directly UNICOM with water tank 2 and outside air, just so can fully supply, and no matter how long used, how much is lost to the air, all can accomplish absolute assurance.
It can be seen that the air energy toilet active inlet valve is a standard mechanized valve.
The active water inlet core valve of the air energy flushing closestool can also be independently used as a waterway control valve, and for the combination mode of the water tank 2 and the core valve component, except the mode provided by the scheme, the core valve component can be independently arranged outside the water tank 2, namely, the core valve is directly arranged on the closestool, and the water tank 2 can be arranged in a toilet wall body at the moment, and the working principle is the same; or the water tank 2 can be replaced by a large-aperture pipeline, and the core valve is directly used as a manual flushing valve at the moment to replace the conventional small-flow mechanical valve, so that the flushing effect is greatly improved, the occupied area of the closestool can be greatly reduced, and the installation space is saved.
The air energy is that a certain amount of air is sealed in the water tank 2 in advance, when pressure water enters, the air is extruded upwards, and when the pressure of the extruded air reaches the water inlet pressure, the water level stops rising; when the water is drained, the water is pushed out by the compressed air, and the device works by utilizing the air pressure potential energy, so the air energy is called.
